Dark matter, an invisible and unknown type of material, is postulated to hold clusters together. X-ray observations have the unique ability to determine the ratio of the mass of the hot gas and the mass of the dark matter in a cluster. The observed values of the gas fraction depend on the assumed distance to the cluster. pdboyer Sat, 06 Nov 2010 19:41:34 GMT http://www.windowsclusters.org/development_tools.htm Windows Clusters Resource Centre, University of Southampton, UK Bookmarks Toolbar Folder > Cluster abhishek_twr Fri, 01 Dec 2006 11:33:42 GMT http://www.windowsclusters.org/cluster%20management.htm Windows Clusters Resource Centre, University of Southampton, UK Bookmarks Toolbar Folder > Cluster abhishek_twr Fri, 01 Dec 2006 11:13:36 GMT http://rss.acs.unt.edu/Rdoc/library/Heatplus/html/00Index.html Bookmarks Toolbar Folder > Data_Vis abhishek_twr Sat, 11 Nov 2006 08:10:51 GMT http://laurie.informatik.uni-bremen.de/clusty/index.php This tiny application lets you cluster your del.icio.us bookmarks into tag clouds.
